Description

Upper garment

The present invention relates to an upper garment, and more particularly, to an upper garment that promotes ventilation in an exercising garment to achieve a cooling effect that lowers temperature.

】 If you exercise continuously for a relatively long time such as marathon or tennis, the body temperature generally tends to rise greatly. In particular, when such exercise is performed in an environment of high temperature and humidity, the increase in body temperature becomes remarkable. Excessive body temperature can lead to decreased exercise performance.

Therefore, it can be expected that the body temperature rise during exercise can be suppressed by making the entire surface or most of the wear with mesh material having high air permeability. In order to improve air permeability and the like, there is known one in which a part of the wear is formed of a mesh material (for example, see Patent Document 1).

Patent Document 1 proposes a sports garment in which front and rear body parts and sleeve parts are connected to each other by a mesh material having a number of vent holes that are more elastic than the body parts and sleeve parts. . In the upper garment for sports, breathability is improved by the mesh material. However, the mesh material is arranged at the connecting part of the front body part and the sleeve part, and the back body part and the sleeve part, so the air taken from the mesh material on the front body side is the mesh material on the back body part of the back part as it is The air flow hardly occurs, and there is room for improvement when focusing on the air flow in the wear.

JP 2000-129512 A

An object of the present invention is to provide an upper garment that promotes ventilation in an garment during exercise and has an improved cooling function.

An upper garment according to an aspect of the present invention is an upper garment including a front body, a back body, and a sleeve part, wherein the sleeve part is located on the same surface side as the front body and the rear part. It has a rear part located on the same surface side as the body, the rear part is formed of a fabric having low air permeability, and the front part has higher air permeability than the rear part.

The front part and the rear part of the sleeve part may be formed of the same fabric, and a plurality of vent holes may be provided in the front part.

A mesh fabric can be used for the front part of the sleeve.

Further, the front body may have a high ventilation portion that is arranged from the collar portion to the shoulder and chest and has a higher air permeability than the rear portion of the sleeve portion.

Further, the fabric constituting the front part and the rear part of the sleeve part is preferably selected from the range of 20 to 150 mm in bending resistance.

Further, the bending resistance of the fabric constituting the front part and the rear part of the sleeve part is set in a range of 20 mm to 150 mm, and the sleeve part is connected to the high ventilation part arranged at the chest and having high air permeability. Good.

Also, the front part of the sleeve part may be formed such that the cuff part at the rear part of the sleeve part is exposed when viewed from the front.

Further, the sleeve portion may have an edge portion that is disposed on the cuff and has higher bending rigidity than the front portion and the rear portion.

The sleeve portion may be formed such that the distance between the sleeve mountain line and the sleeve bottom line increases in parallel or toward the cuffs.

Moreover, you may have the expansion | extension part higher in elasticity than the circumference | surroundings near the buttocks of the said front body and back body.

Preferably, the rear portion has an air permeability of 17 cm ³ / cm ² · s or less, and a difference in air permeability between the front portion and the rear portion is 23 cm ³ / cm ² · s or more.

Further, the plurality of vent holes may be arranged such that the diameter gradually decreases from the sleeve bottom line side of the sleeve portion toward the sleeve mountain line side.

Also, the planar shape of the vent hole can be an ellipse extending in the vertical direction.

In the upper garment according to one aspect of the present invention, the rear part of the sleeve part is formed of a fabric having a low air permeability, and the front part of the sleeve part has a higher air permeability than the rear part. The air flowing in from the front part of the body collides with the material having low air permeability at the rear part, and the air flow toward the center of the body is promoted. By promoting the air flow in this way, for example, an effect of lowering the temperature in the clothes is expected.

Hereinafter, the upper garment of the embodiment of the present invention will be described in detail with reference to the drawings. The upper garment of this embodiment is tennis wear, for example. 1 is a front view of the upper garment of this embodiment, FIG. 2 is a rear view thereof, and FIG. 3 is a side view thereof.

As shown in FIGS. 1 to 3, the upper garment has a main body 1 having a front body 10 and a rear body 11, and a pair of short-sleeved sleeves 2 extending from both upper sides of the main body 1. Yes. A collar portion 13 is provided on the upper portion of the main body portion 1.

The sleeve portion 2 has a front portion 20 located on the same surface side as the front body 10 and a rear portion 21 located on the same surface side as the back body 11.

In order to suppress an increase in the body temperature of an exerciser, it seems that it is sufficient to configure the entire wear using a material with high air permeability such as a mesh material. It has been found that increasing the air permeability and giving a gradient of air permeability to the wear may be able to suppress an increase in body temperature. This verification will be described with reference to FIGS.

9 to 11 are upper garments used for the verification, and specifically, sleeveless garments based on basketware. FIG. 9A and FIG. 9B show the front and back surfaces made of a cloth made of 70% cotton and 30% polyester (hereinafter referred to as normal), FIG. 9A shows the front side, and FIG. 9B shows the back side.

10A and 10B show the entire front and back surfaces made of a mesh material having a higher air permeability than normal fabric (hereinafter referred to as total mesh). FIG. 10A shows the front surface and FIG. 10B shows the back surface. Yes.

FIG. 11A and FIG. 11B are those in which a mesh portion is created by using a mesh material partially on a normal fabric (hereinafter referred to as a partial mesh). As shown in FIG. 11A, the partial mesh portion includes a front chest portion 101,

abdominal portions

102 and 102 at positions slightly inward from both side lines, and a back surface as shown in FIG. 11B. Are provided on the lower part of the neck 103 and part 104 of the lower back from both shoulder ribs.
As shown in FIGS. 12A and 12B, the digital temperature / humidity sensor 110 was attached to the chest and back of the subject, and the temperature inside the clothes during exercise was measured by wearing the upper garment on the subject.

The measurement was performed under the following conditions.
<Environmental conditions>
Indoors with temperature of 25 ° C and humidity of 50% <Exercise conditions>
The following conditions (a), (b), and (c) are performed in order.
Condition (a): Rest in a windless state for 2 minutes.
Condition (b): A resting state of 2 minutes is set in a windy state in which a wind of about 0.5 m / s is sent from the front of the subject.
Condition (c): Running for 20 minutes at a speed of 10 km / h in the same wind condition as in (b).

Under such conditions, the temperature was measured every 30 seconds during the 20 minute exercise of the condition (c), and the average value was obtained. The results are shown in FIGS. 13A and 13B. FIG. 13A is a graph showing the measurement result of the chest temperature, and FIG. 13B is a graph showing the measurement result of the back temperature.

As shown in these graphs, it can be seen that the temperature increase of the partial mesh is suppressed more than both the normal mesh and the total mesh.

Thus, the flow of air in the upper garment of the partial mesh can be considered as a factor that suppresses the temperature rise of the partial mesh compared to the total mesh with good wind passage. Specifically, in the case of a partial mesh, air that has flowed in from the front mesh part due to a running operation, etc., circulates to the back without escaping from the part other than the mesh, and finally escapes from the back mesh part. It is assumed that there is airflow in the clothes. On the other hand, in the case of the total mesh, the air enters and exits regardless of the direction, and it is considered that the air flow unlike the partial mesh hardly occurs.

When the present inventors perform the above-mentioned knowledge, that is, the action of colliding with air, the use of a partially breathable fabric such as a mesh material rather than the entire upper garment As a result, it has been found that there is a case where the increase of the temperature in the garment can be suppressed by promoting the flow of air, and the structure of the upper garment according to the present embodiment has been conceived.

That is, the upper garment according to this embodiment does not form the entire upper garment from a material with high air permeability, but provides a partial air permeability difference to actively promote air flow inside the wear. And each part of the upper garment uses materials with different air permeability. In particular, the rear portion 21 of the sleeve portion 2 is formed of a low-breathable fabric, and the front portion 20 has a higher air permeability than the rear portion 21. Thereby, it is suppressed that the air which flowed in from the front part 20 escapes from the rear part 21 as it is.

In this embodiment, the sleeve 2 is formed using a fabric having a lower air permeability than the front body 10 and the back body 11, and the front portion of the sleeve 2 is provided with a large number of vent holes 22 in the front portion 20. The air permeability 20 is higher than the rear part 21. The vent hole 22 of the front portion 20 can be formed by, for example, a method such as mechanical punching or laser irradiation with respect to the fabric of the front portion 20.

In this embodiment, the front body 10 is provided with a high ventilation portion 12 having a higher air permeability than the rear portion 21 from the collar portion 13 to the shoulder and chest, and the sleeve portion 2 is attached so as to be continuous with the high ventilation portion 12. It has been. The high ventilation portion 12 has, for example, a substantially inverted triangular shape.

In this embodiment, the sleeve 2 is formed based on a raglan sleeve, but is slightly different from a general raglan sleeve. Specifically, the sleeve portion 2 in this embodiment is different from a general raglan sleeve in that the sleeve portion 2 is not directly connected from the collar portion 13, but a high ventilation portion is provided between the collar portion 13 and the sleeve portion 2. 12 is interposed. The sleeve part 2 in this embodiment also includes a part that extends from the shoulder to the chest. In other words, the portion that moves back and forth by arm swing is the sleeve portion 2.

Further, as shown in FIG. 2, the rear body 11 is provided with a high ventilation portion 14 having a substantially inverted triangular shape in a portion extending from the collar portion 13 to the shoulder rib. The high ventilation part 14 has a higher air permeability than the rear part 21. The high ventilation part 14 of the back body 11 is sewn with the sleeve part 2 near the shoulder rib.

In addition, an extension portion 25 formed of a fabric having higher elasticity than the surrounding fabric is provided in the heel portion so that the sleeve portion 2 can move smoothly. In this embodiment, the extending portion 25 is provided near the buttocks of the front body 10 and the back body 11, but the extending portion 25 may be provided only on the front body 10 side.

The cuff of the sleeve part 2 is provided with an edge part 26 having higher bending rigidity than the front part 20 and the rear part 21. By providing the edge portion 26 having a high bending rigidity, the cuffs are not easily deformed, the cuffs are increased in weight, and the centrifugal force during arm swinging acts more, making it easy to secure an air intake port. Become.

Further, in this embodiment, a piping 15 that continues to the cuffs on the front body 10 and a piping 16 that continues to the extension part 25 are provided, and a piping 15 that continues to the cuffs is provided on the back body 11. By providing the

piping

15, 16, the rigidity is increased and deformation of the sleeve portion 2 during arm swing is suppressed. As a result, a space through which air flows is ensured between the skin and the fabric, and the air that has flowed in from the sleeve portion 2 easily flows toward the center of the body.

The fiber used for the fabric constituting the upper garment may be any fiber as long as it is used for general clothing, for example, natural fibers such as cotton, hemp, silk, polyester, nylon, rayon, etc. The chemical fiber can be used. In addition, it is preferable to use the cloth which consists of polyester, for example for the cloth which comprises the sleeve part 2 from a viewpoint of controlling air permeability or bending rigidity.

The air permeability of the front portion 20 of the sleeve portion 2 is set to 40 cm ³ / cm ² · s or more, for example. On the other hand, the rear part 21 of the sleeve part 2 is set so that the air permeability is relatively low, and the air permeability is, for example, 20 cm ³ / cm ² · s or less.

The front part 20 and the rear part 21 may be composed of the same fabric or may be composed of different fabrics. In this embodiment, the front part 20 and the rear part 21 are made of the same fabric, and a plurality of ventilation holes 22 are provided in the front part 20 so that the air permeability of the front part 20 is higher than that of the rear part 21.

In this way, by configuring the sleeve portion 2, air can easily enter from the front portion 20, and air that has entered is prevented from flowing out from the rear portion 21. As a result, the air flowing in from the sleeve 2 can easily flow toward the chest and back.

The front portion 20 and the rear portion 21 of the sleeve portion 2 are set so that the difference in air permeability is, for example, 23 cm ³ / cm ² · s or more.

Of the front body 10 and the back body 11, the air permeability of portions other than the

high ventilation portions

12, 14 is, for example, 100 cm ³ / cm ² · s or more.

The air permeability of the

high ventilation parts

12 and 14 is higher than that of the front body 10 and the back body 11 other than the high ventilation parts, and is, for example, 200 cm ³ / cm ² · s or more.

The air permeability of the fabric can be changed depending on the weaving method, the number of layers (single layer, two layers or more), and the like. For example, in order to lower the air permeability depending on the weaving method, the density of the woven fabric (warp density, weft density) should be as high as possible. Further, the air permeability can be lowered by applying a resin coating to the fabric.

For example, a plain weave, a twill weave, a satin weave, or a combination jacquard can be used as a weave when a fabric is used as the fabric.

The vent hole 22 provided in the front portion 20 of the sleeve portion 2 has, for example, a circular planar shape and a diameter selected within a range of 0.6 mm to 5 mm. By making the diameter 0.6 mm or more, air can easily enter from the vent hole 22. On the other hand, when the diameter is set to 5 mm or less, the exposure of the skin from the vent hole 22 is less noticeable.

FIG. 4 is a view showing an example of a suitable arrangement of the plurality of vent holes 22, and is a plan view in which the sleeve portion 2 is developed. In the sleeve portion 2 shown in FIG. 4, the plurality of vent holes 22 are arranged so that the diameter gradually decreases from the sleeve bottom line 24 side of the sleeve portion 2 toward the sleeve mountain line 23 side. That is, the diameter of the vent hole 22 disposed closer to the sodama line 23 is smaller.

When swinging the arm, the air easily hits the area below the center line in the vertical direction of the front part 20 of the front part 20 of the sleeve portion 2, and the air hitting the area above the center line in the vertical direction is It is considered that there are relatively few. Therefore, if the vent hole 22 in the region near the rear portion 21 (Sodeyama line 23) in the front portion 20 is enlarged, the air flow from there will be lower than the vertical center line of the front portion 20. It is considered that the possibility that the air taken in in the region will escape will be greater. Therefore, by arranging the plurality of vent holes 22 so that the diameter gradually decreases from the sleeve 20 toward the sleeve mountain line 23 side of the front portion 20, air intake and air escape prevention function in a well-balanced manner. Be expected.

Further, the planar shape of the vent hole 22 is not limited to a circle, but may be any shape such as a polygon such as a triangle or a rectangle, or an ellipse. Especially, it is preferable to form in the ellipse shape extended to the up-down direction.

This is because the air that hits the front part 20 of the sleeve part 2 during arm swinging is expected to flow so as to rise along the front part 20, so that the shape of the vent hole 22 is set in the vertical direction. This is because, by making the elongated ellipse shape, it becomes easier to take in more air that flows so as to rise as compared to the case of the circular vent hole 22 having the same area.

By the way, in an athletic competition such as running or tennis where the arm is often shaken in a certain direction such as flexion, extension, abduction, and adduction of the shoulder joint, the sleeve 2 of the upper garment is greatly fluttered by the movement.

If the sleeve portion 2 is so large that the bending resistance of the sleeve portion 2 is low, the shape of the sleeve portion 2 tends to collapse by moving the arm. In that case, the area | region where the fabric of the sleeve part 2 closely_contact | adheres to skin increases, the space through which air flows is not ensured, and the inflow of the air from a cuff is suppressed. Therefore, in this embodiment, the sleeve portion 2 is made of a fabric having high bending resistance.

The preferred range of bending resistance of the fabric constituting the front part 20 and the rear part 21 of the sleeve part 2 is 20 mm to 150 mm. If a fabric having a bending resistance of 20 mm to 150 mm is used, the sleeve 2 is less likely to lose its shape, air passage is ensured, ventilation function is improved, and touch discomfort can be suppressed. That is, when the bending resistance is less than 20 mm, the shape is likely to be lost. Therefore, the bending resistance is preferably 20 mm or more. Further, since the discomfort increases when the bending resistance is greater than 150 mm, the bending resistance is preferably 150 mm or less.

The bending resistance is a value measured based on JIS L 1096A method (45 ° cantilever method).

By the way, the sleeves are generally called set-in where arm holes are taken from the shoulders to the heel and the sleeves are sewn to the body, and the sleeves are taken diagonally from the neck (collar) to the arms (sleeves). There is what is called a raglan sleeve to sew. In this embodiment, as described above, on the basis of the raglan sleeves, the high ventilation portion 12 having a substantially inverted triangular shape is provided between the collar portion 13 and the sleeve portion 2 of the front body 10, and from the sleeve portion 2 to the chest. The fabric having high bending rigidity is used up to the high ventilation portion 12. Thereby, the flow of air is ensured, the flow of air from the sleeve portion 2 toward the collar portion 13 is promoted, and it is expected that the ventilation function is improved.

Also, in order to take in more air from the cuff based on the movement of the arm, it is effective to expand the area of the sleeve 2.

Anatomically, the circumference of the shoulder and the base of the arm are larger in diameter than the upper arm with cuffs. In accordance with this, in general clothing, the diameter around the shoulder shown by the one-dot chain line in FIG. 1 is larger than the diameter of the cuffs. However, from the viewpoint of convection in which more air is taken into the garment from the cuffs, the two

line segments

23a and 24a of the crest mountain line 23 and the cuff bottom line 24 are made parallel to each other, or the crest mountain line 23 and the cuff bottom line 24. It is preferable to form such that the distance between them increases toward the cuffs. Thereby, more air is taken in from the cuffs and convection is promoted, so that the temperature in the clothes is lowered.

As shown in FIG. 1, the cuff of the front part 20 of the sleeve part 2 is formed so that the cuff part of the rear part 21 of the sleeve part 2 is exposed when viewed from the front. In order to take in air efficiently from the cuffs, it is effective to cut the front part 20 of the sleeve part 2 shorter than the rear part 21 in the major axis direction. Accordingly, it becomes possible to apply more air to the rear portion 21 of the back portion of the sleeve portion 2 with respect to the forward swing direction of the arm, leading to promotion of convection. The cuff cutting shape may be triangular as shown in FIG. 1, or any other shape such as a semicircular shape or a square shape, as long as the cuff portion of the rear portion 21 is exposed.

In the above-described embodiment, the front part 20 and the rear part 21 of the sleeve part 2 are made of the same fabric, and the air permeability of the front part 20 is made higher than that of the rear part 21 by providing a large number of ventilation holes 22 in the front part 20. However, the method of providing a difference in air permeability is not limited to this. For example, a cloth in which the front portion 20 is formed using a mesh material and the rear portion 21 is woven at a higher density than the mesh is used. The air permeability of the front portion 20 may be made higher than that of the rear portion 21 by forming the same.

Further, in the above-described embodiment, the sleeve portion 2 is based on the raglan sleeve, and the sleeve portion 2 is provided at a position that moves back and forth by swinging the arm. However, the present invention can also be applied to a normal set-in sleeve portion.

(Example)
Next, a specific embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 5 and 6, the upper garment of this embodiment includes a main body portion 1 having a front body 10 and a back body 11, a sleeve portion 2, a collar portion 13, and

stretch portions

25, 27, and 28. It consists of parts.

In addition, the sleeve part 2 in this embodiment is a part that moves back and forth by swinging the arm, including a part from the shoulder to the chest through the chest.

In this embodiment, the skirt of the back body 11 is formed slightly longer than the front body 10.

The air permeability and blend ratio of each part are as follows.
<Air permeability>
-Front part 20 of the sleeve part 2: 40 cm ³ / cm ² · s
・ Rear part 21 of the sleeve part 2: 17 cm ³ / cm ² · s
Front body 10 and back body 11: 205 cm ³ / cm ² · s
-

Extension part

25,27,28: 89cm < ³ > / cm < ² > * s
The air permeability is a value determined by a method prescribed in JIS L 1096 “Fabric and Knitted Fabric Test Method” using a Fragile-type air permeability tester.
<Mixed spinning rate>
-Front part 20 of the sleeve part 2: 100% polyester
-Sleeve 21 rear 21: 100% polyester
-Front body 10 and back body 11: 100% polyester
・

Extension parts

25, 27, 28: 90% polyester, 10% polyurethane

Here, the front part 20 and the rear part 21 of the sleeve part 2 are made of a fabric woven with the same density using the same 100% polyester fiber, but by providing a plurality of vent holes 22 in the front part 20, There is a difference in air permeability. Further, the sleeve 2 and the front body 10 and the back body 11 are also made of a fabric using the same 100% polyester fiber, but the air permeability is increased by making the density of the sleeve 2 higher than that of the front body 10 and the back body 11. There is a difference.

In addition, the bending resistance of the cloth constituting the front part 20 and the rear part 21 of the sleeve part 2 is 23 mm.

The sleeve 2 and the extension 27 are sewn with the front body 10 near the chest. In this embodiment, the sleeve portion 2 is not directly connected to the collar portion 13, but an extension portion 27 is provided between the collar portion 13 and the sleeve portion 2.

In this embodiment, the sleeve mountain line 23 and the sleeve bottom line 24 are formed in parallel.

As shown in FIG. 5, the cuff of the front portion 20 of the sleeve portion 2 is cut shorter than the rear portion 21 with respect to the long axis direction. The cuff of the sleeve part 2 is provided with an edge part 26 having higher bending rigidity than the front part 20 and the rear part 21.

(Comparative Example 1)
As shown in FIG. 7, Comparative Example 1 is a set-in type normal T-shirt in which the main body 1a and the sleeve 2a are formed of the same fabric having an air permeability of 113.5 cm ³ / cm ² · s. Yes.

(Comparative Example 2)
The comparative example 2 is the same as the example except that the vent hole 22 of the front part 20 of the sleeve part 2 in the upper garment of the example is closed with a tape having no air permeability.

The Example and Comparative Examples 1 and 2 were put on the subject, and the temperature change in the clothing of the subject and the sense of the subject were measured. The number of subjects is 10. Each subject was allowed to swing tennis. A total of 10 sets were swung for about 80 seconds, with one high ball hitting operation and three low ball hitting operations as one set. There will be 40 consecutive swings.

Environmental conditions are 5 ° C temperature, 40% humidity and no wind. As shown in FIG. 8, the temperature was measured by attaching digital temperature / humidity sensors (manufactured by Cisco) to four locations from the arm to the neck. The digital temperature / humidity sensor 41 was attached to the biceps muscle part, the digital temperature / humidity sensor 42 was attached to the deltoid part, the digital temperature / humidity sensor 43 was attached to the shoulder joint part, and the digital temperature / humidity sensor 44 was attached to the upper chest part.

The calculation method was to calculate the difference between the average value of the measured temperature for the first 10 seconds at the start of the swing motion and the average value of the measured temperature for the 10 seconds immediately before the end of the swing motion at four locations, and take the average value at the four locations. That is, body temperature rises by swinging for about 80 seconds, but for each of Example, Comparative Example 1 and Comparative Example 2, the degree of temperature rise is measured by comparing immediately after the start of operation with just before the end of operation. The effect of suppressing the temperature rise was investigated.

As a result, the temperature rise after the exercise was + 0.61 ° C. in the example of the present invention, + 1.42 ° C. in Comparative Example 1, and + 1.34 ° C. in Comparative Example 2. It can be seen that Comparative Example 1 has the highest temperature. And although the comparative example 2 which eliminated the inflow of the wind from a sleeve part was a little lower than the comparative example 1, the increase width of the temperature was about 2 times of the Example.

From this, it was confirmed that the example had an effect of lowering the temperature in the clothes than Comparative Example 1 and Comparative Example 2.

Further, from the demonstration of this embodiment, if the air permeability of the rear portion 21 of the sleeve portion 2 is at least 17 cm ³ / cm ² · s or less, the air taken in from the front portion 10 of the sleeve portion 2 and the cuffs can be removed. The effect of suppressing the air flow is expected.

Moreover, if the air permeability of the front part 20 is set to be higher than the air permeability of the rear part 21 by at least 23 cm ³ / cm ² · s after providing the rear part 21 with low air permeability in this way, The effect of encouraging air flow by sufficiently taking in air is expected.

Next, the senses of 10 subjects were evaluated. A questionnaire was conducted using a visual analog scale (VAS), where “cold” was “1” and “warm” was “10”. As a result, it was 4.3 points in the example, 7.6 points in the comparative example 1, and 6.4 in the comparative example 2. As a result, it was found that this example felt that the temperature in the clothes did not increase.

In the above-described embodiment, the description has been made using tennis wear. However, the present invention is not limited to tennis wear. Therefore, the present invention can be applied to various sports garments.
Although the above-described embodiment has been described using a short-sleeve upper garment, the present invention is also applicable to a long-sleeve garment.
